STEPHEN M. HAMBLIN, OF CENTRAL FALLS, RHODE ISLAND.

LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 651,604, dated June 12, 1900.

Application tiled August 4 1899.

To LM 'ln/tom, it may concern.'

Be it known that I, STEPHEN M. HAMBLIN, a citizen of the United States, residing at Central Falls, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Loom-Shuttles, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference more especially to the means of mounting the shuttle-spindle in the shuttle-body and to the spindle-con-v trolling spring and the means of mounting the latter.

The invention consists in a novel and improved construction of very simple character and compact arrangement and possessing a number of very important practical advantages over what has'been employed heretofore.

The best embodiment of the invention which has thus far been contrived is illustrated in the accompanying drawings, in Which-- Figure l is a representation of portion of a loom-shuttle having the said embodiment of the invention applied thereto, the parts being mainly in section on a vertical plane ex- Fig. 2 is a side elevation of the tubular and forked mounting to which reference is made in the course of the following description. Fig. 3 is a View of the said mounting in plan.

In the drawings, l designates the shuttlebody.

2 is the shuttle-spindle. For the support of the spindle 2 and its controlling-spring a mounting 3 is provided. This mounting is constructed with a cylindrical body portion 3l and a head 32 at one end of said body, the said head being shown of slightly-greater diameter than the latter, although this is not essential, the said head being forked, as shown most clearly in Fig. 3. The space or slot 33 between the arms 34 34 of the fork is of a width slightly greater than the thickness of the head 2l of the spindle 2. The head 2l of the spindle is placed between the arms 34 34 of the forked head of mounting 3 and secured there by means of the pivot-pin 4, (shown in Fig. 1,) a hole 35 being formed in each of the arms 34 for the reception of the Serial No. 726,154. (No model.)

said pivot-pin. The pivot-pin 4 isriveted down at the outer sides of the arms 34 34er is otherwise secured to the said arms. The body 3l of the mounting 3 is made tubular from the forked head nearly to the opposite end 36, which last is closed. (See Fig. l.)

Within the tubular body 3l of the mountingv are placed the spiral spring 5, Fig. 1, and the' headed follower The inner end of spring 5 bears against the closed end 36 ot` the tnbular body 3l of mounting 3, while the outer end of the said spring bears against the inner' face of the head of the follower 6, the spring being compressed between the said end 36 and the head of the follower. The stem of the said follower fits inside the spring. The outer face of the follower 6 bears against a projection or nose 22, which is formed on the spindle-head 2l, above the pivot 4 thereof, and thereby the spindle is held pressed by the action of spring 5 into the position in which it is shown in` Fig. l---namely, in its depressed or normal Working position-extending in line with the mounting 3. This position is determined by the contact of a projection 23, which is formed on the spindlehead below, the pivot 4 thereof, with the end wall of the slot 33 in the head of mounting 3. When the spindle is tilted upward ou pivot 4, it is held in an upraised position by the action of spring 5 in holding follower 6 pressed against the face 24 of the spindlen head. p

For the reception of the mounting 3 a hole is bored from the shuttle-cavity 7 longitudinally into the end portion of the shuttle-body, this hole being of sufficient diameter and length to receive the entire mounting, the entering end of the said hole being enlarged, as in Fig. l, to receive the slightly-enlarged forked head of the mounting and also in order to permit free play of the spindle-head as it is turned up and down upon pivot 4.

For the purpose of securing the assembled parts in place after the application of the same to the shuttle-body a pin 8 is driven vertically through the end ofthe shuttle-body, as shown in ,Fig l. The said pin passes through a hole 37, which is formed through the solid portion of the closed end 3G of the mounting 3.

It will be perceived that the construction shuttle-body in preparing it for the recep' tion of the spindle, spring, &c., and in itting and applying the latter thereto; also, that only a single fastening-pin S is used for connecting all the parts with the shuttle-body and that this pin readily may be driven out when removal of the parts for inspection or repairs are necessary; also, that the said securing-pin is passed through the shuttlebody vertically, and hence cannot occasion injury to the reed-dents in consequence of contact of a projecting end thereof with the latter.

What is claimed as the invention is In a loom-shuttle, the combination with a shuttle-body having a lon gitudinal hole bored in the end portion thereof; of a tubular mounting in said hole, said tubular mounting having a forked head and a closed rear end having a solid portion; a spindle pivoted between the arms of the said forked head; a spring follower within said tubular mounting, and a fastening-pin passing vertically through the said shuttle-body and the said solid rear portion of said tubular mounting, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
